Description

Technical Field

[0001] The present invention relates to the technical field of building pipeline installation, and specifically relates to an installation and fixing device for building water supply and drainage pipelines. Background Art

[0002] In buildings, it is inevitable to lay a large number of water supply and drainage pipelines. After the water supply and drainage pipelines are laid according to the route, they need to be fixed to prevent large shaking during water supply and drainage from damaging the pipelines.

[0003] For example, the Chinese patent with the publication number "CN219841152U" discloses "an installation and fixing device for building water supply and drainage pipelines". Its main structure includes a fixed seat and a fixing plate fixed at the bottom of the fixed seat, and also includes a fixing sleeve and a U-shaped sleeve. The U-shaped sleeve cooperates with the fixing sleeve to fix the drainage pipe. The fixing sleeve is fixed on the fixed seat. Symmetric slots are provided on the fixed seat. Both ends of the U-shaped sleeve are slidably connected to the slots. Both ends of the U-shaped sleeve are provided with clamping slots, and a first magnet is fixedly connected to the bottom of the clamping slots. This installation and fixing device for building water supply and drainage pipelines can fix both ends of the U-shaped sleeve when the U-shaped sleeve is inserted into the slot through the setting of the clamping mechanism. By controlling the mechanism to control the sliding of the sliding groove and the slider in the sliding groove, the second magnet slides into the clamping slot to limit the U-shaped sleeve, preventing the U-shaped sleeve from falling off. The magnetic force between the first magnet and the second magnet enables the U-shaped sleeve to cooperate with the fixing sleeve to fix the drainage pipe.

[0004] When the above installation and fixing device for building water supply and drainage pipelines clamps the pipeline, it fixes both ends of the U-shaped sleeve when the U-shaped sleeve is inserted into the slot. However, the fixing sleeve and the U-shaped sleeve themselves are rigid structures, and their clamping radius for the pipeline is a fixed value, resulting in a fixed effective contact radius of the fixing sleeve and the U-shaped sleeve for the pipeline. Therefore, the adaptability of this installation and fixing device for building water supply and drainage pipelines to the clamping radius is relatively low. In addition, the effective contact surface of the fixing sleeve and the U-shaped sleeve for the pipeline is relatively low, resulting in a relatively large clamping pressure exerted on the pipeline per unit area, which is not conducive to the effective service life of the pipeline. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an installation and fixing device for building water supply and drainage pipelines, which uses a deformable textile soft belt and a rubber clamping base to wrap and clamp the water supply and drainage pipelines, with stronger fit, thereby increasing the effective contact area with the water supply and drainage pipelines to reduce the clamping strength exerted on the water supply and drainage pipelines per unit area.

[0021] To achieve the wrapping clamping effect on the pipe, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5, it is necessary to set up a wrapped clamping mechanism 2, which is internally provided with a rotatable movable disk 21, a textile soft belt 25 that passes through the movable disk 21 and can wrap and clamp the upper half of the pipeline, a rubber clamping base 24 fixedly installed above the movable disk 21 and capable of supporting and clamping the lower half of the pipeline, a piston plate 211 placed directly below the movable disk 21 and capable of moving downward under liquid pressure, and an embedded moving plate 214 that can move with the piston plate 211 and drive the bottom structure of the textile soft belt 25 to move. Insert the pipeline between the textile soft belt 25 and the rubber clamping base 24, start the hydraulic system, and the liquid enters the interior of the longitudinal component activity cavity 27 through the first liquid injection channel 29. Under the action of the liquid pressure, the piston plate 211 moves downward, so that the entire textile soft belt 25 moves downward until the pipeline is clamped between the textile soft belt 25 and the rubber clamping base 24, achieving the wrapped clamping effect on the pipeline.

[0022] For the specific structure of the wrapped clamping mechanism 2, please refer to Figure 3 , Figure 4 and Figure 5, including a fixed base 23 and a cylindrical hollow housing 26. Inside the disk body of the movable disk 21, there are two symmetric belt perforations 22. On the upper surface of the movable disk 21, a fixed base 23 is fixedly installed. At the top of the fixed base 23, a rubber clamping base 24 is embedded. The belt body of the textile soft belt 25 passes through the belt perforation 22 and both open ends are located below the movable disk 21. The bottom open ends of the textile soft belt 25 are fixedly embedded inside both ends of an embedded moving plate 214. At the bottom of the movable disk 21, there is a cylindrical hollow housing 26 integrated with it. Inside the cylindrical hollow housing 26, there is a longitudinal component activity cavity 27. At the top of the longitudinal component activity cavity 27, there is a liquid limit flow cavity 28 with a relatively smaller structural radius. On the side of the cylindrical hollow housing 26, there is a first liquid injection channel 29 for injecting liquid into the liquid limit flow cavity 28 and a liquid valve is installed inside. At the bottom end of the cylindrical hollow housing 26, there is a rod perforation 210 connecting the structure below it and the bottom end of the longitudinal component activity cavity 27. Inside the cylindrical hollow housing 26 and located in the longitudinal component activity cavity 27, there is a piston plate 211 that can move axially along the longitudinal component activity cavity 27. At the bottom end of the piston plate 211, a longitudinal telescopic rod 212 passing through the rod perforation 210 is fixedly installed.

The structural shape of the cross-section of the rod perforation 210 is the same as that of the cross-section of the longitudinal telescopic rod 212, both being polygonal structures, and the structural dimensions of the cross-section match those of the cross-section of the longitudinal telescopic rod 212.

[0023] In order to achieve an adjustable pipe clamping angle, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7, it is necessary to set up an angle-variable connection mechanism 3, which internally has a hollow ring body 33 fixedly installed directly above the bottom fixing plate 1 and in a hollow state, an inner rotating sphere 39 installed in the center of the hollow ring body 33 in a rotatable manner and capable of driving the movable disk 21 to rotate, and an annular air film 37 that can achieve a locking effect on the inner rotating sphere 39 under liquid pressure. When achieving the wrapped clamping effect on the pipeline, due to structural limitations, the movable disk 21 will undergo an adaptive angular rotation in the hollow ring body 33. After the movable disk 21 no longer rotates, liquid is injected into the interior of the annular liquid flow chamber 36 through the liquid system. Under the action of the liquid pressure, the annular air film 37 will deform inward until the inner surface of the annular air film 37 wraps around the outer surface of the inner rotating sphere 39 with a certain pressure, achieving the locking effect on the inner rotating sphere 39.

[0024] Regarding the specific structure of the angle-variable connection mechanism 3, please refer to Figure 6 and Figure 7 , including a top fixing plate 31. A plurality of sector fixing plates 34 integrally formed with it are provided on the outer circumferential surface of the hollow ring body 33. The sector fixing plates 34 and the top fixing plate 31 are fixedly connected by longitudinal support rods 32. A spherical cavity 35 with both ends open is provided in the center of the hollow ring body 33. An annular liquid flow chamber 36 with an open inner side is provided inside the hollow ring body 33. The top fixing plate 31 is provided with an annular air film 37 at the intersection of the annular liquid flow chamber 36 and the spherical cavity 35. A second liquid injection channel 38 integrally formed with it and used to inject liquid into the interior of the annular liquid flow chamber 36 is provided on the outer circumferential surface of the hollow ring body 33. An inner rotating sphere 39 that can rotate is placed inside the spherical cavity 35 of the hollow ring body 33. A hollow structure 310 with both ends open is provided in the center of the inner rotating sphere 39. A plate fixing groove 311 is provided at the horizontal center of the inner rotating sphere 39 in the hollow structure 310.

The edge structure of the movable disk 21 is fixedly installed inside the plate fixing groove 311. The structural radius of the outer circumferential surface of the inner rotating sphere 39 matches the structural radius of the spherical cavity 35. The depth of the spherical cavity 35 is less than the structural radius of the outer circumferential surface of the inner rotating sphere 39. The thickness of the inner rotating sphere 39 is greater than the depth of the spherical cavity 35, and the structural diameter of the outer circumferential surface of the limiting ring structure 312 is greater than the calibers at both ends of the spherical cavity 35.

[0025] To achieve the function of adjusting the installation height, please refer to Figure 1 , Figure 2 and Figure 8, it is necessary to set up an installation height adjustment mechanism 4, which is internally provided with a first external threaded rod 46 and a second external threaded rod 47 connected to the ends of the bottom fixing plate 1 and the top fixing plate 31, a threaded sleeve 41 threadedly connected to the first external threaded rod 46 and the second external threaded rod 47 and capable of changing the distance between the first external threaded rod 46 and the second external threaded rod 47 when rotating, and a polygonal limiting rod 411 inserted at the axis of the first external threaded rod 46 and the second external threaded rod 47 and capable of preventing relative rotation between the first external threaded rod 46 and the second external threaded rod 47. When the threaded sleeve 41 is rotated in a fixed direction, since the spiral direction of the first thread structure 44 is opposite to that of the second thread structure 45, and during the rotation process, due to the presence of the polygonal limiting rod 411, the first external threaded rod 46 and the second external threaded rod 47 will not rotate relative to each other. Therefore, the distance between the first external threaded rod 46 and the second external threaded rod 47 will change, thereby realizing the function of adjusting the working height.

[0026] For the specific structure of the installation height adjustment mechanism 4, please refer to Figure 8 , including a first thread structure 44 and a second thread structure 45. One end of the threaded sleeve 41 is provided with a first internal thread cavity 42 with an inwardly concave structure, and the other end of the threaded sleeve 41 is provided with a second internal thread cavity 43 with an inwardly concave structure. The rod body of the first external threaded rod 46 is installed inside the first internal thread cavity 42 through the first thread structure 44, and the rod body of the second external threaded rod 47 is installed inside the second internal thread cavity 43 through the second thread structure 45. The opposite ends of the first external threaded rod 46 and the second external threaded rod 47 are provided with a polygonal limiting cavity 410 with an inwardly concave structure. A polygonal limiting rod 411 inserted into the interior of the polygonal limiting cavity 410 is fixedly installed at the center of the threaded sleeve 41. One end of the first external threaded rod 46 is provided with a first connecting plate 48 integrally formed with it and fixedly connected to the bottom fixing plate 1, and one end of the second external threaded rod 47 is provided with a second connecting plate 49 integrally formed with it and fixedly connected to the top fixing plate 31. The cross-sectional structure of the polygonal limiting cavity 410 is the same as that of the cross-section of the polygonal limiting rod 411, both being polygonal structures, and the cross-sectional dimension of the polygonal limiting cavity 410 matches the cross-sectional dimension of the polygonal limiting rod 411. The first thread structure 44 includes an internal thread structure arranged inside the first internal thread cavity 42 and an external thread structure arranged on the rod body of the first external threaded rod 46. The second thread structure 45 includes an internal thread structure arranged inside the second internal thread cavity 43 and an external thread structure arranged on the rod body of the second external threaded rod 47, and the spiral direction of the first thread structure 44 is opposite to that of the second thread structure 45.

[0027] In use, the bottom fixing plate 1 is fixedly installed at the foundation through bolts, and at the same time, it needs to be used in cooperation with a hydraulic system capable of controlling liquid pressure. The liquid circuit of the hydraulic system is docked with the first liquid injection channel 29 and the second liquid injection channel 38. By rotating the threaded sleeve 41 directionally, the distance between the first outer threaded rod 46 and the second outer threaded rod 47 will change, thereby adjusting the working height of the textile soft belt 25 and the rubber clamping base 24. Insert the pipeline between the textile soft belt 25 and the rubber clamping base 24, start the hydraulic system, and the liquid enters the interior of the longitudinal component activity cavity 27 through the first liquid injection channel 29. Under the action of the liquid pressure, the piston plate 211 moves downward, so that the whole textile soft belt 25 moves downward until the pipeline is clamped between the textile soft belt 25 and the rubber clamping base 24. When realizing the wrapped clamping effect on the pipeline, due to structural restrictions, the movable disk 21 will rotate adaptively at an angle in the hollow ring body 33. After the movable disk 21 no longer rotates, inject liquid into the interior of the annular liquid flow cavity 36 through the liquid system. Under the action of the liquid pressure, the annular air film 37 will deform inward until the inner surface of the annular air film 37 wraps the outer surface of the inner rotating sphere 39 with a certain pressure, realizing the locking effect on the inner rotating sphere 39, thereby fixing the pipeline.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
